8.7.15 NILF Low Frequency Beacon
The low frequency beacon NILF is contained in a white plastic enclosure with a slim design that is suitable
for surface mounting on walls or at a door post. The NILF is powered by three 1.5V "C" alkaline batteries.
In situations where battery power is not suitable the unit can be powered by certified ECS power supplies
(see Section 4.)
An optional NIRX transceiver module can be mounted onto the NILF circuit board to monitor the NILF
through a heartbeat signal. The NIRX will send out a tamper alarm upon front cover removal detection or
send a low battery alarm.
The NILF operates at 125 kHz producing a spherical magnetic field with a range of up to 8.86 feet (2.7
meters). The magnetic field strength can be adjusted to suit the requirements. A master/slave
configuration can be used to extend the range of the LF field
Interconnection" on page 182.
DIP switches are used to set the 12bit ID code, to select the transmission rate allowing a suitable interval
between 0.1 - 2s and to set the output power, ranging from 0.30m to

NILF Installation
